Eleven test-pits of varying sizes were excavated using a mechanical excavator equipped with a toothless ditching bucket. Seven of the test-pits (TP2, TP5-TP10) were excavated to obtain information on ground conditions, the presence of contamination and infiltration characteristics. Three test-pits (TP1, TP3 and TP4) were excavated to determine the level of survival of the Roman circus remains and the arrangement of service runs where they were believed to cross the circus walls. One test-pit (TP11) was excavated for a soakage test. Following the completion of the soakage test, the excavation area was extended to 5.5m x 5.5m in size to ascertain whether any archaeological features or deposits survived in the area of a proposed soakaway. <1> In addition, seven windowless sample holes (WS01- WS07) and three hand-auger pits (HA01-HA03) were excavated by geotechnical engineers to assess shallow ground conditions and obtain soil samples. All ten of these holes were hand-excavated to a depth of 1m below modern ground level under archaeological supervision. The robbed-out foundation of the outer cavea wall of the Roman circus was located in Test-pit (TP)1 and 3. The inner cavea wall was also shown to be completely robbed out in TP3. <1> The monitoring in 2013 followed the trial-trenched evaluation of the site in 2007 (CAT report 438). <2>
